I split my case and the slippery slope began..After buying new OEM P/C's, sending off the cams, rockers, Heads, crank and rods rebalanced, grind and cleaned , rebuilt back wiring harness, turbo rebuild here shortly and a whole slew new parts, ARP head studs for mine...Not to include new tools, books to make the job easier..I bought new for most parts since I was there...Could have saved a few but hey...I wanted assurance since I do not want to know something crapped out later and 13k later the block is back together. Ready for the cams to be timed...
